Tower of Dawn (Throne of Glass, #6)

by Sarah J. Maas

Sartaq steered Kadara southward, soaring high above the snowcapped peaks. “Those kingdoms also didn’t anticipate an army that conquered from behind, by taking routes that few would risk.” He pointed to the west, toward a pale band along the horizon. “The Kyzultum Desert lies that way. For centuries, it was a barrier between the steppes and the greener lands. To attempt to conquer the southern territories, everyone had always taken the long way around it, giving plenty of time for the defenders to rally a host. So when those kingdoms heard the khagan and his hundred thousand warriors were on the move, they positioned their armies to intercept them.” Pride limned his every word. “Only to discover that the khagan and his armies had directly crossed the Kyzultum, befriending local nomads long sneered at by the southern kingdoms to guide them. Allowing the khagan to creep right behind them and sack their unguarded cities.”
